A successful serial entrepreneur and a seasoned chemical engineer with a decade of experience at one of the nation’s premier national labs have come together to develop and scale a new direct air capture technology that mimics the architecture of a human lung.
The founders of the startup, named Spiritus after the Latin word for “breath,” began work in December 2021, and the company is officially coming out of stealth on Wednesday, with the announcement of an $11 million funding raise led by prominent Silicon Valley venture capital firm Khosla Ventures, with other investors including Page One Ventures.
Spiritus has built a novel approach to direct air carbon capture that relies on a material that absorbs carbon dioxide passively. Critically, Spiritus has developed a particular architecture that mimics the alveoli in the lungs in order to maximize the surface area for carbon dioxide to make contact with the material.
This lung-like material, technically called a “sorbent,” will be shaped in round balls and laid out like artificial fruits in a carbon-capture orchard, CEO Charles Cadieu and CTO Matt Lee told CNBC in a phone interview on Tuesday.
When the lung-like “fruit” have been collected from the carbon “orchard,” they will be put in a container, where low heat will be applied to remove the carbon dioxide. The desorption process will be powered by clean energy to ensure the process is a not adding emissions to the atmosphere. Once the CO2 has been removed from the lung-like fruit, the sorbent can then be returned to the carbon orchard and reused.

‘Mother nature’s the true artist’
Lee worked at Los Alamos National Lab from September 2012 to June 2022 on a variety of chemical engineering advanced material projects, including some with national security and defense applications, as well as heat shields and laser fusion fuel target pellets similar to those used at the Lawrence Livermore National Laboratory to achieve a key milestone in nuclear fusion. He is a specialist in colloid science, which is the study of materials where particles of one substance are suspended in another.
Lee hadn’t worked on carbon capture technology applications until Cadieu inspired him to consider the problem. The pair had known each other for about 15 years through a family friend and had enjoyed keeping tabs on each other’s projects.
When Cadieu approached Lee to consider carbon capture, Lee approached the problem with a philosophy he has carried through much of his career: “Mother nature’s the true artist and she’s had a lot more practice than we have had,” Lee told CNBC. The other prong of his philosophy is summarized by a Leonardo da Vinci quote Lee recounted: “Simplicity is the ultimate sophistication.”
That’s why they looked at lungs.

“Lungs are very well rehearsed at doing this — taking a large volume of air and then dispersing it or spreading it out over an extraordinary high amount of interface that the alveolimake with other parts of the body,” Lee told CNBC. That’s important because while carbon dioxide levels in the atmosphere are at record high levels, carbon dioxide is still diluted and makes up a relatively small percentage of the air.
“In order to capture some significant quantities of carbon dioxide on your sorbent, you simply have to expose it to a lot of air — a massive amount — and so finding the structure that can simultaneously give you that highly efficient contact with a large amount of active surface per unit volume enables you to have a process that is viable, feasible, economical,” Lee told CNBC.
That third component — economical — is critical in the direct air carbon capture field, and is part of what drew Khosla Ventures to make its first direct air capture investment in Spiritus.
“We’ve been watching on the sidelines evaluating all the technologies,” Rajesh Swaminathan, partner at Khosla Ventures, told CNBC in a phone conversation on Tuesday. Direct air capture is still a nascent industry and therefore very expensive right now, but Spiritus uses less energy than most of the other competitors in the space, Swaminathan said.
The absorption of carbon dioxide is passive, and the desorption process, where the carbon dioxide is removed from the “fruit” made with the lung-like material, takes a comparatively low amount of energy, Swaminathan said.

“A lot of direct air capture processes, they require either a lot of high heat — and ours requires low heat — or they require a lot of energy, even if low heat, and ours is less than half of what’s been previously achieved by other solutions,” Cadieu told CNBC. “So this is another part of this overall equation that drives down low costs.”
The U.S. Department of Energy has a public initiative called the “Carbon Negative Shot,” which is its name for the push to drive innovation that can capture carbon dioxide, remove it from the atmosphere and store it for less than $100 per metric ton. Spiritus is driving towards this $100 per metric ton goal.
Spiritus will partner with companies specializing in carbon sequestration to take that removed carbon and put it away.
Cadieu says the artificial carbon orchards that Spiritus plans to build are more efficient than biologic trees and so take a smaller land footprint to absorb carbon dioxide than biologic forests. When the carbon captured with artificial trees is stored, it also has the advantage of sequestering carbon permanently. When biologic trees decompose after they die or burn in a fire, carbon they contain is released back into the atmosphere.
“We’re able to remove about 1,000 times more carbon dioxide than a forest can. And so this solution is actually far more efficient than forestry for removing carbon dioxide from the atmosphere per acre,” Cadieu said.

Nvidia has just shelled out over $900 million to hire Enfabrica CEO Rochan Sankar and other employees at the artificial intelligence hardware startup, and to license the company’s technology, CNBC has learned.
In a deal reminiscent of recent AI talent acquisitions made by Meta and Google, Nvidia is paying cash and stock in the transaction, according to two people familiar with the arrangement. The deal closed last week, and Enfabrica CEO Rochan Sankar has joined Nvidia, said the people, who asked not to be named because the matter is private.
Nvidia has served as the backbone of the AI boom that began with the launch of OpenAI’s ChatGPT in late 2022. The company’s graphics processing units (GPUs), which are generally purchased in large clusters, power the training of large language models and allow for big cloud providers to offer AI services to clients.
Enfabrica, founded in 2019, says its technology can connect more than 100,000 GPUs together. It’s a solution that could help Nvidia offer integrated systems around its chips so clusters can effectively serve as a single computer.
A spokesperson for Nvidia declined to comment, and Enfabrica didn’t provide a comment for this story.
While Nvidia’s earlier AI chips like the A100 were single processors slotted into servers, its most recent products come in tall racks with 72 GPUs installed working together. That’s the kind of system inside the $4 billion data center in Wisconsin that Microsoft announced on Thursday.
Nvidia previously invested in Enfabrica as part of a $125 million Series B round in 2023 that was led by Atreides Management. The company didn’t disclose its valuation at the time, but said that it was a fivefold increase from its Series A funding.
Late last year, Enfabrica raised another $115 million from investors including Spark Capital, Arm, Samsung and Cisco. According to PitchBook, the post-money valuation was about $600 million.
Tech giants Meta, Google, Microsoft and Amazon have all poured money into hiring top AI talent through deals that resemble acquihires. The transactions allow the companies to bring in top engineers and researchers without worrying about the regulatory hassles that come with acquisitions.
The biggest such deal came in June, when Meta spent $14.3 billion on Scale AI founder Alexandr Wang and others and took a 49% stake in the AI startup. A month later, Google announced an agreement to bring in Varun Mohan, co-founder and CEO of artificial intelligence coding startup Windsurf, and other research and development employees in a $2.4 billion deal that also included licensing fees.
Last year, Google made a similar deal to bring in the founders of Character.AI. Microsoft did the same thing for Inflection, as did Amazon for Adept.
While Nvidia has been a big investor in AI technologies and infrastructure, it hasn’t been a significant acquirer. The company’s only billion-dollar-plus deal was for Israeli chip designer Mellanox, a $6.9 billion purchase announced in 2019. Much of Nvidia’s current Blackwell product lineup is enabled by networking technology that it acquired through that acquisition.
Nvidia tried to buy chip design company Arm, but that deal collapsed in 2022 due to regulatory pressure. In the past year, Nvidia closed a $700 million purchase of Run:ai, an Israeli company whose technology helps software makers optimize their infrastructure for AI.
On Thursday, Nvidia announced one of its most sizable investments to date. The chipmaker said it’s taken a $5 billion stake in Intel, and announced that the two companies will collaborate on AI processors. Nvidia also said this week that it invested close to $700 million in U.K. data center startup Nscale.

CrowdStrike shares popped about 13%, a day after the cybersecurity firm issued better-than-expected long-term guidance at its investor day.
The company on Wednesday said it expects net new annual recurring revenues to grow at least 20% in 2027, ahead of analysts’ expectations. CrowdStrike plans for ARR to hit $10 billion by 2031, and then double to $20 billion by 2036.
“CrowdStrike is by far the most advanced security platform in the industry, and the plethora of AI-based solutions announced today will further separate CrowdStrike from the competition,” wrote Wells Fargo analyst Andrew Nowinski in a note following the event.
Some Wall Street firms also boosted their price targets.

Nvidia CEO Jensen Huang said that the company’s $5 billion investment and technology collaboration with Intel comes after the two companies held discussions for nearly a year.
Huang said that he communicated personally with Intel CEO Lip-Bu Tan about the partnership. He called Tan a “longtime friend” on a Thursday call with reporters after the companies announced that Nvidia would co-develop data center and PC chips with Intel as part of the investment deal. On the call, Tan said he and Huang have known each other for 30 years.
“We thought it was going to be such an incredible investment,” Huang said.
Nvidia said it will collaborate with the chipmaker to create artificial intelligence systems for data centers that combine Intel’s x86-based central processors with Nvidia’s graphics processors and networking.
Intel will also sell CPUs for PCs and notebooks that integrate Nvidia graphics processors, or GPUs.
The transaction itself took a few months to come together, Intel’s revenue chief Greg Ernst wrote in a LinkedIn post, adding that the agreement was reached on Saturday.
The investment highlights how the fortunes of the two companies have switched atop Silicon Valley’s pecking order as a result of the AI explosion ushered in by OpenAI’s launch of ChatGPT in late 2022.
Intel shares are down 31.78% in the last five years, while Nvidia shares are up 1,348% as of opening prices on Thursday. Nvidia is worth over $4.25 trillion, while Intel is only worth $143 billion.
How Intel and Nvidia will collaborate
For decades, the most important part in a PC or server was the central processor, and Intel dominated the market for those chips. But AI infrastructure, like the machines in the $4 billion data center Microsoft announced on Thursday, often needs two or more Nvidia GPUs for every one CPU.
Nvidia AI systems, like the NVL72 used by Microsoft, come with Arm-based CPUs, instead of Intel x86-based CPUs. On the call, Huang said Nvidia will soon support Intel’s CPUs in its NVLink racks for AI.
“We’ll buy those CPUs from from Intel, and then we’ll connect it into super chips that then becomes our compute node, that then gets integrated into a rack scale AI supercomputer,” Huang said.
Nvidia will also contribute GPU technology to Intel chips that ship in laptops and PCs, which is an underserved market, Huang said. In total, the addressable markets for the two product collaborations are worth $50 billion, Huang said.
“We’re going to become a very large customer of Intel CPUs, and we’re going to be a large supplier of GPU chiplets into Intel” chips, he said.
Huang said the deal with Intel will have “no” impact on Nvidia’s business relationship with Arm.
Thursday’s investment deal is focused on the relationship between Nvidia and Intel’s product division, not its foundry. The two companies, however, did not rule out future foundry partnerships.
“We’ve always evaluated Intel’s foundry technology, and we’re going to continue to do it, but today, this announcement, is squarely focused on these custom CPUs,” Huang said. Nvidia currently uses Taiwan Semiconductor Manufacturing Company to manufacture its chips.
The collaboration will use Intel’s packaging, which is a part chip manufacturing that occurs toward the end of the process and combines several chip components into a single part that can be installed in machines.

Tan said he was grateful for Nvidia’s vote of confidence.
“‘I’d like to thank Jensen for the confidence in me, and our team and Intel will work really hard to make sure it’s a good return for you,” Tan said.
Last year, Intel’s board removed previous CEO Pat Gelsinger because of rising costs in its manufacturing business and the company’s failure to gain a foothold in AI chips. In March, Intel named Tan, a well-connected investor who had turned around chip software firm Cadence Design Systems, its new chief executive.
Tan has focused on cutting costs and raising money in his short tenure leading Intel even as the future of the company’s manufacturing business, called Intel Foundry, remains unclear.
In addition to the $5 billion from Nvidia and $8.9 billion from the U.S. government, Intel has taken a $2 billion investment from SoftBank, sold a majority stake in its ASIC subsidiary Altera to Silver Lake for $3.3 billion and sold $1 billion in stock from Mobileye, its self-driving car subsidiary.
Intel has also cut significant staff, saying in July that it would eliminate 15% of its workforce by the end of the year.
The company develops its own chips as well as manufacturing them. It wants to manufacture chips for companies like Nvidia or Apple, but has yet to secure them as customers. Analysts say Intel needs a big foundry client to signal that its technology is stable and ready for volume production.
But cutting-edge chip manufacturing is expensive, and Intel has signaled that if it can’t get enough customers, it may not continue investing in its foundry. That could spark a reaction from Washington, whose politicians and lobbyists consider Intel to be strategically important for the nation because it is the only American company capable of manufacturing the most advanced chips.
The Trump administration took a 10% stake in Intel in August. Intel was previously in line to receive $8.9 billion in grants and loans from the CHIPS Act, but the Trump administration asked and received an equity stake in the chipmaker in exchange for the money.
Huang was with Trump this week in England to attend a State Dinner at Windsor Palace and announce new projects and investments in the U.K. But the Trump administration wasn’t involved in this deal, according to a White House official and Huang.
“Intel’s new partnership with Nvidia is a major milestone for American high-tech manufacturing,” White House spokesman Kush Desai said in a statement.
